The Sogionti or Sogiontii were a Gallic tribe dwelling around present-day Sisteron during the Iron Age.
They are mentioned as Sogionti (var. songi-, sonti-) by Pliny (1st c. AD),[1] and as Sogionti and Sogion[ti]or(um) on inscriptions.[2][3]
The meaning of the name remains obscure. Guy Barruol compared the first element to the toponym Soio.[4]
The Sogiontii lived in the middle valley of the Durance river, around present-day Sisteron (Segustero).[5] Their territory was located north of the Reii, west of the Bodiontici, east of the Vocontii, and south of the Sebaginni.[6]
They were probably part of the Vocontian confederation.[7][8]
They are mentioned by Pliny the Elder as one of the Alpine tribes conquered by Rome in 16–15 BC, and whose name was engraved on the Tropaeum Alpium.[1]
